To @ZZ cl2/om t may concern.:

Be it known that l, Lotns" BERNHARD BARON, a citizen of the United States of America, residing at 23S-2&0 City Road,

in the city and county of London, England, have invented new .and useful linprove ments in Cigarette-Making Machines, ot which the following is a specification.

This invention relates to cigarette making machines and it refers to the cut-ol mechanism of machines of the continuous rod type in which one or more knives is or are employed `for cutting the rod into lengths, said ,knives being` so mounted and operated as to follow a substantially elliptical path and having a variable. speed tlirou-ghout certain portions of said path.

The present invention has for its object certain improvements designed to` simplify the construction of cutting mechanism by re- `ducing the number of wearing parts to a minimum wherebyA V loss of etliciency due 'to slackness in the parts under wear is avoided; the life of the machine as a whole increased; and finally the cost of maintenance, due to the necessity for repeated adjustment to compensate for wear of the parts or the renewal of said parts is considerably reduced.y

Another object is to provide a cutter having a quick return movement yduring the cutting action whereby it is possible to increase the speed of the machine with a consequent increase in the output.

According to this invention a knife carrying carriage isremployed and arranged to move in parallelism to the cigarette rod. Means are provided torimparting reciprocal motion to the carriage and a cutting means thereon in the line of movement of said rod, this movement longitudinally of the rod being secured by a purely crank motion, the movement of the cutting means transversely of the rod being secured by a second crank motion driven through elliptical gear pinions.

In order that the invention may be the better understood drawings are appended in which Fig. 1 is a front view of part of a machine embodying the present invention,

Fig. 2 is a plan,

Fig. 3 is an end view,

Fig. 4 is a vertical section on line A A Sil Fig. 2, looking in the direction of the arrow ai,

Fig. is a sectional view showing more clearly the arrangement by which the trans verse angular movement of the connecting rodactuating the knives is permitted,

Fig. is a vertical section on line B B Fig. 2, looking in the direction of the arrow y,

Fig. 7 is a horizontal section on line C C Fig'. 1.

Referring to the accompanying drawings, in which only such parts ot the main portion of the machine are illustrated as are essential to the proper understanding of the invention, 1 indicates the frame ot the machine. 2 the. main shaft of the machine. Mounted upon the end of the shaft 2 is a pinion 3 transi'nitting motion through pinions l and 5 to a shaft 6 supported in brackets 7. 8, secured to the frame of the machine. Mounted upon the shaft 6 is a bevel pinion 9 Fig. 2 engaging a second pinion 10 attached to a shaft 11 supported in a. bearing 12 on bracket 13 bolted or otherwise secured to the rear wall of frame 1.

Secured to the inner end of shaft 11 is an elliptical pinion 14 in gear with a second elliptical pinion 15 mounted on a center of revolution for rotary movement secured to the inner end of a spindle 16 supported in a bearing 17l on bracket 17 also sccured to the rear wall ot' frame 1. It will he undcrstood that the teeth of the pinions 111, 15, are so proportioned and pitched as to permit ot the 'driving engagement and running oit the two plnions. Secured respectively to the pinions 1l, 15, and arranged concentrically to the centres ot rotation thereof are discs 14, 15 each provided upon its outer face with an undercut channel 15b, 15 Fig. 4, to engage suitably shaped nuts carrying pins 17, 17"L which pins are so mounted that their centres are not co-incident with the centres of rotation of the discs.

To the pin 17 upon the disc 14. connected one cnd of a link 1lb the opposite end of which is connected to the lower end o1 a lever 18 pivotally mounted at 18 in a bracket 18b secured to the end ot the trame of the 1nachine. Preferably the cn'neC-,tion ot the link let to its pin 17 is effected through a ball bearing or other friction rc ducing device.

' `portion yofthe machine frame.

Obviously the discs 14a, 15TY may be mount-- yed upon and rotate with the spindles of theV Y pinion's 14,15 instead ofbein'g connected toV the pinions themselves.

V- Levers Vor arms 24a, ,25a yare Vpivota'lly 'mounted at their` lfower ends upon spindles 24", 25, running transversely of Vthelower A knife carriage generally denoted b y 19a` Vcomprises a back member `19 to the ends of whichare connected vby meansY of rods 2O fro-nt members 1n the form of plates 21, 21a,

Downwardly extending portions 2lb, 21c arerprovided upon the plates 21, 21', the

downwardly .extending portions 21'), 21c being'provided with bearings for a shaft 29. A tie bar 3() extendsfrom the downwardly extending portion 2lb to the .downwardly eX- tending portion 21,

f'Arreciprocatory motion parallel, to the cigarette Arod/w is imparted tothe carriage 19a the desired motion bein-g transmitted from f i' fthe Vaf.o'rementioned pinf'lr' through link'14b ftofthe lower end of lever'18 to thevv upperf,

l. end of' which lever is Ap ivotally connected onefendfof a 'link 27 the other end of link' 2T is connected-to `arm'24f;

*A boss 28?, Figsl and 6, clamped upon the shaft 29 isv provided-with a pair ofjup- @wardlyrextending arms 28b 28D, the ends of l"which are provided with bearings 28e, 28d,

through which a'spindle 28a'passes upon Ythe endsof ,which spindle the circular knives 28 v are secured;

(.llan'ipedto the shaft 29 is a boss 31`hav- Y ing 'a Vrearwardly extending projection 32V terminating in a pin 33, which` pin is connected to the upperend of Ya link' 34Y by means Vof al universal joint 34 the lower lend of link 34 being connected to the p1n17a of the disc 15a Vby means of a second universal joint 34", as shown more clearly in Figs. 4,

5 and 6. Y

Y The universal joints 34 and .84"are provided for the purpose of lallowing the link 34 sufficient angular movement to permit it torock the'shaft 29 by means of the projection 32 in Yorder to-Y cause the knives 28 jto vmove toand fromfthe cigarette rod 'w lwhich passes through guides 28d.

' The guides 28d areV supported byvrods 21f,

llfloimted upon the shaft@y -is sheave 39 "from which motion is transmittedbyi means of a belt 39a'to a second sheave 'mounted Vupon one end .offa,spindleV carried in a bearing Bhsupported'by a bracket'a. Y

'The other end of the spindle 37 has mounted thrreon a third sheave 36 which drives the knives 28 by means of an elastic belt on thev shaft 6. By'this means the action of z theknives may bestopped without stopping theishaft 2. Y l v -K It will be understood thatthe knives 28 are caused. to travel forward to cut the cigarette rod 'w and backward to clear the saine by means of t-he'eccentrically mounted pin lvjof the discla, which acts on `the link 34, tilting the arm 32 and so rocking the shaft 29.

Itis necessary that the knives after having travelled forward at a certain speed `should travel back to clear the rod w at a muchv greater speed; This is accomplished `by the provision of the ellipticalgear pinions 14'and 15.

`'Ihe'carriage 19a is caused to travell along "with the cigarette rodlduring the cnttingf foperation, the amount of its movement being governed'by the length of the cigarette f tha-tit is desired to be produced.

Both the amount of forward movenientof the knives and the length of movement of 'the carriage may be altered at will by shifting the positions of the pins 17, 17a respectively in the groovesin the discs 14, 15a.

The o-peration of thepa-rts is as follows :f-f i `Motion being imparted toshaftr2 istrans# mitted'through pinions 8, 4and 5 torshaft 11V to which Lis secured theV elliptical geary 'wheel 14, said Wheel 14 being in gear with andr driving the second ellipticalggearwvheel 1.5 which thus has a varying speedy; Asthe lever 18 is connected through link'14b to the pin 17 upon disc 14athe rotationV of the said pinion 14 will cause the lever 18'to be rocked and a reciprocatory motion will be imparted to the knife carriage through link 27 connected to the upper end of arm 24?, which armis connected to the said carriage, the movement imparted'being in a parallel lplane to the line of Ythe .rodto becut into lengths.`

At the same moved along in the direction inrwhichv the rodis'travelling, the disc l5` associated with the pinion 15, by means of pin 17a,"operates iccA .f Gand through pinions) and 10vr to theshaft time as the carriage is being 'the link 84, to cause the knivesto move transversely of the rod in order to vcut the same. During the aforesaid'operations the knives are driven by the beltfpassing overthe-A sheave 786,: the said belt Vbeing driven bythe rlhe tension of the belt 35 may be adjusted by means of al jockey pulley y'.

By properly selecting the dimensions of the elliptical pinions it is possible to secure the required variations in the speed of travel of the4 knives at the desired portions of their travel.
